AMINO ACID COMPOSITION OF UREDOSPORES OF PUCCINIA GRAMINIS TRITICI
Keyword(s):
Uredospores of Puccinia graminis var. tritici (race 56) were analyzed quantitatively for total free amino acids and ninhydrin-positive substances by ion-exchange chromatography. Extracts of these substances were obtained by leaching the spores and by re-extracting leached spores with boiling water. Thirty-five ninhydrin-positive compounds were found and identified. The leach extract differed quantitatively from the extract obtained by boiling although both contained the same 35 substances. It is proposed that there are easily extractable ninhydrin-positive substances coating the spore wall and ninhydrin-positive substances in the protoplasm that can be extracted only with difficulty.
